Sound of Rain May Help Plant Seeds Decide When to Grow
Rice and related seed types can sense the sound of rain impacting the soil or water surface above them and respond by accelerating germination at depths where impulsive rain sound is sufficiently intense to intermittently shake statoliths from contact with cell membrane receptors and trigger gravitropic growth mechanisms.

New experiments with rice suggest that the acoustic vibrations of falling droplets can jolt dormant seeds into growth, offering the first direct evidence that plants can sense natural sound.
